On a high-level, osc-setcoremem is a SuperCluster tool that assists in making changes to the CPU and memory configurations of one or more dedicated domains running on a SuperCluster compute node. osc-setcoremem helps in removing (park) resources from dedicated domains for licensing purposes. Also using osc-setcoremem, some of the CPU and memory resources can be removed from one dedicated domain and added to remaining dedicated domains. Root domains are ignored by default.

Any user with no prior knowledge of Oracle VM Server for SPARC (also known as Logical Domains) administration, and how the operating system organizes CPU and memory resources into different locality groups (lgroups) can easily reconfigure the dedicated domains to achieve desired (or in some cases close to the desired) CPU, memory configurations. Only those users with root privileges can run the tool.
